方法：收集30名志愿者模拟3种行为状态(平静、不安、激动)10分钟的手臂和腿部活动图数据，记录观察到的参与者运动(头部、躯干、四肢)的数量。结果：参与者的平均年龄为34.7岁，其中60%为女性。各州之间的平均活动有显著差异(P<；.0001；平静[平均值=.48]，躁动[平均值=2.16]，躁动[平均值=3.75])。手臂(P<；.0001；平静[均值=6.8]、躁动[均值=28.5]、躁动[均值=52.6])和腿部(平静[均值=3.5]、不安[均值=18.7]、激动[均值=37.7])的平均动作图测量结果有显著差异。活动描记数据可以提供患者在各种行为状态下活动的客观指标，这些数据可以为这些状态之间的比较提供一个标准。
BACKGROUND: Actigraphic data during simulated participant movements were evaluated to differentiate among patient behavior states.METHODS: Arm and leg actigraphic data were collected on 30 volunteers who simulated 3 behavioral states (calm, restless, agitated) for 10 minutes; counts of observed participant movements (head, torso, extremities) were documented.RESULTS: The mean age of participants was 34.7 years, and 60% were female. Average movement was significantly different among the states (P < .0001; calm [mean = .48], restless [mean = 2.16], agitated [mean = 3.75]). Mean actigraphic measures were significantly different among states for both arm (P < .0001; calm [mean = 6.8], restless [mean = 28.5], agitated [mean = 52.6]) and leg (P < .0001; calm [mean = 3.5], restless [mean = 18.7], agitated [mean = 37.7]).CONCLUSION: Distinct levels of behavioral states were successfully simulated. Actigraphic data can provide an objective indicator of patient activity over a variety of behavioral states, and these data may offer a standard for comparison among these states.
